To all whom it may concern:

Be it known that l, Anson Sorinonnnn, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of l/linnesota,have invented certain new and useful improvements in Hangers forStormhash, of which the following is a specification.

lhis invention relates to hangers for storm sash and the like, andhas'for its object to provide a hanger so constructed as not to rattleon its support.

A further object of the invention is to provide a hanger which may bestamped and formed out of sheet metal requiring no subsequent filing ormachine work aS far as the working parts are concerned.

It has been found very difficult to produce an article of this kind fromsheet metal which will not require to be made with a great deal of playin the parts so as to render it practical from a manufacturingstandpoint. For this reason hangers rattle under wind action, it havingbeen found difficult to produce a die cut pivot support in hangers ofthe class described. which will be compensatory in its movement, so asto insure snug ts between the working parts to avoid rattling. In thepresent invention the movable partof the hanger is constructed with acompensatory curve adapted to co-act with the stationary part of thehanger in a manner during the movement thereof so as to constantlysnugly span a points whereby rattling prevented. in the drawings:

Fig. is an enlarged diagrammatic view illustrating the various stagesofthe move ment of the movable ineml eron the stationary member, showingthe development of an irregular compensatory curve. 7

A represents a portion of the window frame, and B the window sashfitting into the opening of the frame, C designates the stationarysupporting bracket member and D the supported movable sash supportingmember. .The stationary member is struck from a flat sheet of metal andbent to form oppositely disposed alined screw plate parts to form thescrew plate 1 having screw holes 2 whereby the member may be firmlyscrewed to the lintel of the frame A either flush with or adjacent theed e thereof.

Centrally widthwise 01' the screw plate the latter is bent to form theoutwardly extending hook shaped hollow lug 2, having parallel spacedwalls 3 forming collectively a relatively thick fiat vertically disposedlug,

the bend thereof being such as to produce a rounded outer surfaceconstituting an out wardly and upwardly inclined edge 4i.

Above, the lug is formed with a transverse, upwardly opening ll-shapednotch or crotch 5, one wall 6 thereof being shown parallel with the edge4-, Extendingat right angles to the wall 6, is, what may betermed thebottom of the crotch 7, the width thereof being such as to snuglyreceive the thickness ,of the metal sheet out of which the member l) isstruck. Continuing from the bottom '3' and extending upwardly andrearwardly to the plate 1, and terminating a distance below theupperedge of the latter to formthe blank space 8, is the wall 9 of thecrotch. Y

Byhmaking the lug; as described, namely, with a crotch having a wideopening and a relatively widebottom, the male member of the die (notshown) employed in cuttingthe blanks (not shown) will be of durableshape having no acutely angled cutting parts, thereby simplifying andcheapening the process of manufacture. The movable member D is formedwith a fastening plate 10 having suitable screw holes 11 whereby it isfirmly secured, as by means of screws, to the sash B. The underside ofthe fastening plate is flush, when mounted, with that of the plate 1.

Extending upwardly and outwardly and beyond the top of the sash to aposition directly opposite the member 0 (when the adapted to looselyreceive the lug 2 widthwise, the angle of the loop portion being similarto the angle of the edge 4 so as to be parallel with the latter. Thesupported member is blanke'dsoas to form when bent, two'inturnedoppositely and longitudinally g member including a plate, and anoutstanddisposed parallel cam lugs 13 extending a distance beyond theends of the opening 12, so as to form a guide (F 1g, 1) for d1rect1ngthe sash in'the processor hanging. When the upper edge 14 of the thesupported position (Fig. 2) opening (which is in the state in which-itleft the die) seats squarely on the bottom 7 of the crotch the latterconstituting a pivot bearing as is best shown in Fig.

the window is in closed member hangs in the vertex of said crotch. 1 p

The cam lugs are formed with what may be termed a compensatory curve l4,or, in other words a curve so formed as to compensate for the change ofposition of the center of rotation 15 when the squared edge 14 is causedto turnon' the bottom of the crotch 5 Three stages of this turningmovement are illustrated by three kinds of lines (solid -heavy dash-anddot and light dash and dot) each indicating the relative sition' of thecenter 15 the face 16 of theplate l. The position indicated in solidlines a requires the edge of the 'cam lug to extend to b so as topermit-no play between the face 16 and the wall 6. Theheavy dash lines 0indicate P with respect a to that the center 15 has moved toward theface 16, and that the distance between the latter and the center 15 hasbeen shortened while the dotted lines indicate. that the center 15 isagain changed in position. Thus, thecam edge of the lugs is designedtocompensate for the change in position of the By constructing the camlugs of play, at any time exists between the wall 6 and center 15. asdescribed no appreciable amount the face 16, thereby preventing rattlingof the sash in'its hanger. f I

To prevent rattling of the sash longitudinally, the curve of the edge I?of the lug 2 is also developed from the movement of the center 15. InFig. 1, the sash is shown extended as far as the usual sash fastenermechanism at jthe bottom of the sash (not 7 position) is the loop por- 7Vof-jthe drawings. Virtually,

face thereof being shown) permits. The lower edge18 of the opening 12snugly passes over this edge when the cash is swung the curve changinging vertically disposed lug thereon formed at its top with an upwardlyopening crotch and having a curved lower edge, and asupl ported windowsash member having an openiiig of such shape as to movably receive saidlug and be pivotally: supported by means of the upper edge of saidopening on the bottom of said crotch, the lower edge of said openingmoving snugly over said curved lower edge when said supported member ismoved, said supported member having a curved part extending from saidpivotal support to said plate the curved formed so as to snugly fitthereaga inst during themovement of said supported member.

2.111 a hanger, a stationary supporting member including a plate and anoutstanding lug thereon formed at its top with an upwardly openingcrotch, a supported sash member depending from said crotchso'as to pivoton the-bottom thereof, and lugs having a curved edge on thesupported-mem her extending rearwardly away from said 7 pivot to saidplate so that their curved edges willconta'ct therewith whereby tomaintain a snugly fitting relation between said sup" porting andsupported memberduring the movement of the latter.

3. In a hanger, a stationary supporting member comprising in part anoutstanding. lug formed at its top with anupwardly opening crotch, asupported sash member having an apertureto loosely receive said lug andbeing adapted tobe hung from above into said crotch so as to swingoutwardly therefrom, said sash member being formed with spacedguidemembers extending over the sides of, said lug to loosely rethem inthe process for'the purpose set ceive said lug between of hanging thesash forth. 7 V V In testimony whereof Iafiix my signature.
